The electrochemical equivalent of platinum is 5.0 x 10-7kgC-1 to plate-out 1.0kg of platinum, a current of 100A must be passed through an appropriate vessel for
-
5.6 hours
- 56 hours
- 1.4 x 104 hours
- 2.0 x 104 hours
The correct answer is: A
Explanation
m = Itz1 = 100 x 5 x 10-7 x t
t = 20,000sec
= 5.6hrs
